This RFC series is for Chelsio iSCSI target offload driver(cxgbit.ko). cxgbit.ko registers with iSCSI target transport and offloads multiple CPU intensive tasks to Chelsio T5 adapters. Chelsio T5 adapter series has following offload features for iSCSI - -TCP/IP offload. -iSCSI PDU recovery by reassembling TCP segments. -Header and Data Digest offload. -iSCSI segmentation offload(ISO). -Direct Data Placement(DDP). Please review this series.
